I am assuming you have the new Infinity Touch control (black). If the screen is blank, you've either lost low voltage power (an issue at your furnace) or the unit isn't properly seated on the backplate. Pull the thermostat off of the wall and reseat it properly and if this does not work, you'll probably need a pro to come troubleshoot low voltage issues.

The green leaf is "eco mode." It generally will reduce the running pressures of the system, meaning you spend less on energy and have longer runtimes, but it will reduce cooling capacity. On the less brutal days this is a great option. It's better for the system and better for the energy bill. However, there WILL be days where eco mode simply won't keep up.

A P6 on a Carrier air con means a communication error between the inverter and power supply PCB on the outdoor unit. In most cases, both boards will require changing. Check with a Carrier Agent first. I can imagine that replacement of both will be a costly exercise.
